Subject: fix: improve shortcut text of Accelerator

This patch makes three changes to Accelerator::GetShortcutText to improve shortcut display text in menus:

1. Ctrl-Alt-<Key> accelerators show as Ctrl-Alt-<Key> instead of as Ctrl-<Key>
2. F2-F24 accelerators show up as such
3. Ctrl-Shift-= and Ctrl-Plus show up as such
